FIREARM.

Application filed December 11, 1912.

To all whom it may concern Be it known that I, INoHEsTnR BENNETT, a citizen of the United States, residing at N w Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Firearms; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in-

Figure 1 a view in right hand side elevation of a gun constructed in accordance with my invention. Fig. 2 a broken view of the gun in side elevation, showing the band fastened to and depending from the barrel for the support of the forward end of the tubular magazine.v Fig. 3 a view of the gun in vertical cross-section on the line ab of Fig. 2. Fig. at a corresponding view on the line 0(Z of Fig. 2. Fig. 5 a broken view in horizontal section on the line e-f of Fig. 2, showing the abutment-rib upon the barrel taking into the grooves provided for its reception in the inner faces of the spring clamping-arms of the band. Fig. 6 a view of the barrel and the band in broken longitudinal section, with the forward end of the magazine shown in side elevation. Fig. 7 a broken view in side elevation of the barrel, showing its abutment-rib. Fig. 8 a broken, reverse plan View thereof. Fig. 9 a detached perspective view of the band. Fig. 10 a detached plan view of the bushing or tie-piece of the band. Fig. 11 a view thereof in front elevation.

My invention relates to an improvement in that class of magazine firearms in which the action is operated by a forearm sliding upon a tubular magazine, the specific object of my present invention being to provide an improved band for supporting the forward end of the tubular magazine from the gunbarrel, whereby the band is prevented from being loosened or displaced with respect to the barrel by the action of the sliding forearm.

VJith these ends in view, my invention consists in a firearm having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claims.

In carrying out my invention, as herein Specification of Letters Patent.

Patented July 22,1913.

Serial No. 736,175.

shown, I provide the gun-barrel 2 at a point forward of its center, with an integral segmental abutment-rib 3, embracing the lower face and sides of the barrel, formed with square rear and forward edges furnished on opposite sides of the center of its lower face with a pair of abutment-notches 41: having square inner ends for engagement, as shown in Fig. 4., by the extreme inner ends of a pair of binding screws 5 mounted in the op posite ends of a removable bushing or tiepiece 6 having a longitudinal bore 7 located in a chamber 8 formed in the split band 9 just above the vertical center thereof. The said screws are formed with flanged heads which extend beyond the periphery of the tie-piece 6 at the ends thereof, and enter shallow recesses 10 in the outer faces of the spring clai'nping-arms 11 of the band, so that when the screws are turned inward into the threaded ends of the tie-piece 6, they will draw the said arms 11 of the band 9 together and clamp the same tightly upon the barrel 2. To produce the arms 11 the band is formed with a central vertical split 12 which adapts it to be sprung over the abutment-rib 3 for the reception of which the said arms 11 are formed upon their inner faces with grooves 13 exactly conforming to the cross sectional form'of the rib 3. The engagement of the ends of the screws 5 with the square inner ends of the abutment-notches in the rib 3 effectually holds the band 9 from any rotary movement upon the barrel 2 in a plane at a right angle to the longitudinal axis thereof, while the square edges of the rib 3 prevent any movement of the band 9 either forward or back upon the barrel 2.

For the clearance of the lower face of the barrel 2, the tie-piece 6 is formed in its upper face with a clearance-notch 14: conforming to the curvature of the barrel 2 and intersecting the central bore 7 of the tiepiece 6 so as to expose the inner ends of the screws 5 and permit them to enter the abutment-notches t. The lower face of the tie-piece 6 is formed with a central rectangular notch 15 for the reception of a flat leaf-spring 16 applied to the upper face of the tubular magazine 17 and employed to hold the sliding forearm 18 forward by friction when the gun is taken down as fully shown and described in United States Patent No. 933,253, granted September 7, 1909, on the application of Thomas C. Johnson, assignor to the Winchester Repeating Arms Company.

The tubular magazine 17 is detachably connected at its rear end with the gun-frame or receiver 19 in any approved manner, as well as the rear end of the barrel 2, these features of take-down guns forming no part of my present invention. At its forward end, the magazine 17 is furnished with a radially movable rod-like lever 20 for unscrewing the magazine at its rear end from the receiver 19 at the time of taking down the gun, and turning it' back into place again in assembling the gun.

I may now explain that in tubular magazine guns of the forearm type in which the forearm slides back and forth upon the magazine, the band employed to support the forward end of the magazine is constantly subjected to vibration tending to loosen it and particularly subjected to a severe shock when the forearm is thrown against the band preparatory to taking the gun down. My improved abutment-rib 3 and band 9 sustain the vibration and the shocks referred to and prevent the band from getting loose or out of place with respect to the gun-barrel 2. Thus as the abutment-rib 3 is ar ranged transversely with respect to the bar rel and extends upward on each side thereof, it prevents the band from movement back and forth in the direction of the barrel, and also prevents the band from rocking in a vertical plane. Furthermore, as the abutment-rib 3 extends below the barrel and is provided with notches for co-action with the ends of the binding-screws 5, the same are in this manner removed, as it were, from proximity to the bore of the barrel which is thus protected against being defaced by the action of the said screws in case of any rocking of the band, whereas when corresponding notches for the same purpose are formed directly in the lower face of the barrel as has heretofore been customary, the stock in the barrel is liable to be pushed upward into the bore thereof when strain is placed upon the screws, whereby the integrity of the bore of the gun is impaired, since the displacement of the stock referred to is plainly visible in looking into the bore of the gun. The described disfigurement of the bore is particularly apt to take place when the band is tipped in the vertical plane in case the screws are turned up tight into notches formed directly in the barrel.

These several objections are avoided by my present construction.

I claim:

1. In a firearm, the combination with a barrel formed upon its lower face with a segmental transversely arranged abutmentrib extending upward on each side of the barrel, of a tubular magazine, a sliding forearm mounted thereupon, and a band adapted to support the forward end of the magazine and formed with a groove for the reception of the said rib in holding the band in place upon the barrel whereby the band is held against longitudinal and tipping movement with respect to the barrel.

2. In a firearm, the combination with a barrel formed upon its lower face with a segmental transversely arranged abutmentrib extending upward on each side of the barrel, of a tubular magazine, a sliding forearm mounted thereupon, and a band adapted to support the forward end of the magazine and formed with a groove for the reception of the abutment-rib of the barrel whereby the band is held against longitudinal and tipping movement with respect to the barrel.

3. In a firearm, the combination with a barrel formed upon its lower face with a segmental transversely arranged abutmentrib extending upward on each side of the barrel and formed in its lower face with abutment-notches, of a tubular magazine, a sliding forearm mounted thereupon, a chambered band adapted to support the forward end of the said magazine and to be clasped upon the barrel formed with a groove for the reception of the said abutment-rib, a removable bushing or tie-piece located in the chamber of the said band, and screws entering the ends of the said bushing 0r tiepiece and engaging with the arms of the band for drawing the same upon the barrel, and entering the said notches in the lower face of the said rib for preventing the band from rotating upon the barrel whereby the band is held against longitudinal and tipping movement with respect to the barrel.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
